My approach might also be an option.
My shack is on the second floor of the house. My antenna is a ground mounted vertical with the coax buried under the grass out back. I rented a hammer-drill a few years back (well, OK, about 35 years back) and drilled a hole in the brick just above the poured concrete foundation of the house. I set a large conduit (forgot the size, but just pick one) and set it into the brick with RTV sealant. On the outside of the conduit, I installed a "corner-pull" which is a right angle fitting that has a weather-proof, removable cover plate to facilitate feeding stiffer cables through the right angle bend. The right angle points downward, to avoid moisture ingress. The coax comes out of the ground right under the corner-pull. Once the cable gets into the basement, it runs across the ceiling in the unfinished utility area of the basement to the double-stud wall where the plumbing vent stack goes upstairs. The coax (and a host of other network and phone cables) runs up next to the vent pipe to the second floor where there is an access panel in a closet. The coax exits the wall into the closet, runs across the closet floor and along the baseboard of the shack, through another closet, and exits the wall right behind my operating desk.
This is, unfortunately, a wordy way of trying to explain that you can bring a cable into the basement, then up inside a wall to your shack. Use whatever cover/access plate you like to protect the exit point from the wall. Ease of service is key. Use your imagination, and your local home center.
